Solar energy is the radiation from the Sun capable of producing heat, causing chemical reactions, or generating electricity. The total amount of solar energy received on Earth is vastly more than the world's current and anticipated energy requirements. If suitably harnessed, solar energy has the potential to satisfy all future energy needs.
Understanding the science behind solar energy involves delving into the principles of physics, chemistry, and engineering. In this blog, we’ll explore the key scientific concepts that make solar energy possible and provide a table summarizing these principles. 1.1 1. The Sun as an Energy Source: 1.2 2. Electromagnetic Radiation: 1.3 3.
This opening chapter introduces the energy emitted from the sun, the instruments to measure solar radiation and different photovoltaic cell types that are used in different implementations. Electromagnetic radiation emitted by the nearest star reaches the earth as solar radiation. Sunlight consists of visible and near visible regions.
Solar radiation (Rs) is defined as the amount of energy radiated from the sun in the form of electromagnetic waves that reaches the Earth surface. You might find these chapters and articles relevant to this topic. A. Fernández-García, ... M. Pérez, in Renewable and Sustainable Energy Reviews, 2010
The intensity of solar radiation is directly proportional to the time of radiation. The length of sunshine varies with latitude and season. The solar radiation energy reaching the Earth is only a small part of the total solar radiation energy, but its role is quite large. Solar radiation is the main source of energy on the Earth's surface.
The solar energy reaching the Earth's surface is estimated at approximately 130,000 Gtoe (toe = tons of oil equivalent) annually (Widén and Munkhammar, , 2019). The electromagnetic radiation emitted by the sun is called solar radiation, and its unit is represented W/m 2 (Carrasco et al., 2017).
